Pollution in cities threatens public health, making water quality monitoring essential to detect hazardous substances. This invention introduces an optochemical detector that utilizes localized surface plasmon resonance (LSPR) and optical interferometry for trace lead ion detection in water, offering ppb-level (part per billion) sensitivity without the need for DNA materials or amplification additives. It features a compact, robust design suitable for on-the-go applications, enabling prompt and low-cost testing. Particularly effective for ensuring water safety by detecting lead ion concentrations as low as 10 ppb, aligning with WHO guidelines, it has potential applications in environmental monitoring and public health safety.
